Product Description

SJ301 EL12 EM12K welding flux



Standard: GB/5293-1999 F4AO-H08A F5AO-H10Mn2



EQUIV: AWS-A5.17 F6A0-EL12 F7A0-EM12K
 


SJ 301 EL12 EM12K welding flux is a kind of fluoride-alkaline-type slag-serial sintered flux, mesh 10-60


meshes (2.0-3.0mm), basicity 1.6-1.8. It has great capacity of sulphur removal, phosphor removal and


anti- rust. The technology has a good performance, easy to deslag and with fine appearance of weld,


even in the narrow gap of deep slope entrance. The metal welding seam has a good plastic -toughness,


with low diffusion of hydrogen and fine cold and heat crack resistance.




Usage:

The flux is fit for the submerged arc welding of low carbon steel and low alloy steel, as well as the fast


single-way and double-surface welding of thin steel sheet. And it is usually used for the sumberged arc


welding of liquefied gas storage tanks, gas bottles, and pipeline steel.




Package:

25kg per kraft paper bag; 1000kg per Jumbo bag




Cautions:

1. The welding flux must be baked for 2hours at the temperature of 300-350ºC before build up welding



2.Some foreign substances such as rust , grease and moisture on the weldment should be removed


before welding.
